There are a number of caveats to getting that large sum, however. You must port your number from another carrier, you must purchase a 4G LTE smartphone with new device activation and you must trade-in your existing device. The trade-in must be in good working condition and the new line must remain active for at least six months.
In addition, if you switch now to an XL or XXL plan, you get an extra 2GB of bonus data, per month, forever.
